Maintenance and repair
Roofs made of bitumen tiles require minimal maintenance and repair. Periodically check the roof for
problem areas or problems. Take a look to make sure there are no missing shingles or loose branches
and debris. It is also important to clean the gutters from time to time.
If there are exposed areas in place of the tiles, they should be replaced as soon as possible to prevent
damage to the roof.
Types of construction
The most common type of bitumen shingles that homeowners install is either fiberglass shingles, or tiles
based on organic mat. The tile will either have an asphalt-impregnated organic substrate made of
cellulose fibers such as wood or paper, or it may have a fiberglass-based substrate or mat.
Fiberglass shingles can have the following general characteristics:

Fiberglass shingles can have the following general characteristics:
— High wear resistance and durability
— Less weight and thinner material
— Higher fire resistance than organic varieties
— Longer guarantees
Tiles made of organic mat may contain 40 percent or more of asphalt than fiberglass, which makes it
heavier, thicker and more expensive.
However, they are also durable, flexible and able to absorb more damage over time.
The side exposed to atmospheric influences is covered with a harder bitumen material, and then sealed
with special filler granules to create a surface exposed to atmospheric influences. Then a heat-sensitive
adhesive or a «self-adhesive strip» of mastic is applied over the protrusions, so the tiles are glued to
each other after being nailed in a staggered manner.
